We report on a search for the flavor-changing neutral current decays B-d,s(0) --> mu(+)mu(-), B+ --> mu(+)mu(-)K(+), and B-0 --> mu(+)mu(-)K(*0) using data from <p(p)over bar> collisions at root s = 1.8 TeV, collected with the Collider Detector at Fermilab during the 1992-1993 running period. We find no indication of such decays, and we set the following 90% confidence level upper limits on branching ratios: B(B-0 --> mu(+)mu(-)) < 1.6 x 10(-6), B(B-s(0) --> mu(+)mu(-)) < 8.4 x 10(-6), B(B+ --> mu(+)mu(-)K(+)) < 1.0 x 10(-5), and B(B-0 --> mu(+)mu(-)K(*0)) < 2.5 x 10(-5).

Abstract

We report on a search for the flavor-changing neutral current decays B-d,s(0) --> mu(+)mu(-), B+ --> mu(+)mu(-)K(+), and B-0 --> mu(+)mu(-)K(*0) using data from collisions at root s = 1.8 TeV, collected with the Collider Detector at Fermilab during the 1992-1993 running period. We find no indication of such decays, and we set the following 90% confidence level upper limits on branching ratios: B(B-0 --> mu(+)mu(-)) < 1.6 x 10(-6), B(B-s(0) --> mu(+)mu(-)) < 8.4 x 10(-6), B(B+ --> mu(+)mu(-)K(+)) < 1.0 x 10(-5), and B(B-0 --> mu(+)mu(-)K(*0)) < 2.5 x 10(-5).
